Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 200571-38-6 Ethyl 5-Oxo-3,5-di(3-pyridyl)pentanoate |A-Oxo-|A-3-pyridinyl-3-pyridinepentanoic Acid Ethyl Ester.
200571-38-6 Ethyl 5-Oxo-3,5-di(3-pyridyl)pentanoate |A-Oxo-|A-3-pyridinyl-3-pyridinepentanoic Acid Ethyl Ester (CAS 200571-38-6), molecular formula C17H18N2O3 and molecular weight 298.34 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 200571-38-6 Ethyl 5-Oxo-3,5-di(3-pyridyl)pentanoate |A-Oxo-|A-3-pyridinyl-3-pyridinepentanoic Acid Ethyl Ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 200571-38-6 Ethyl 5-Oxo-3,5-di(3-pyridyl)pentanoate |A-Oxo-|A-3-pyridinyl-3-pyridinepentanoic Acid Ethyl Ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
